BOX rAsrENEa.

Application filed January 6, 1922. Serial No. 527,295.

T 0 all whom it may concern Be it known that EDWIN B. STRANGE, a citizen of the United States, and resident of Riverdale-on-theHudson, in the county of Bronx and State of New York, have invented certain new and useful Improvements in Box Fasteners, of which the follow-- ing is a specification.

This invention relates'to has for its object to provide a simple and effective fastener for holding down the lids of boxes and similar containers which are filled with goods and shipped, and returned when empty. A common type of container of this character is a small ice-box in which certified milk is shipped, and numerous other uses exist wherein a tight and yet-simple fastener is desired, particularly where there is a gasket or other packing between the lid,

and the box, which requires to be tight.

The invention is in general principle simi lar to toggle types of bottle fasteners modified by the necessity of providing both resiliency and the toggle joint without going inside the front face of the box. This result is effected in this invention by mounting on the box front a plate With a resilient projecting loop, to which is pivoted the lever, there being intermediately pivoted to the lever a hasp which engagesa hook on the box cover, the result being that when the lever is thrown up the hasp releases the cover, and when thrown down the cover is resiliently pulled down on the box. The lever is either latched in closed position, frictionally or by the toggle action, or may be tied down a with a wire seal, thus being acceptable for shipment by common carriers.

In the accompanying drawing:

Figure 1 is an elevation;

Figure 2, a front view, and Figure 3 a vertical section showing the fastener open. 7 V 1 represents the box front; 2, the cover; 3 the front plate, attached by screws 4; 5 the top plate, attached by screws 6; 7 the hook'on plate 5 for hasp 8; 9 the lever, and 10 a loop for a wire seal or pin.

The front plate 3 is provided with a resilient outwardly extending wing 11 having a loop 12, to which the lever 9 is attached. The'lever 9 is not plane, but is bent outwardly as at 13, then inwardly as at 14, and

box fasteners and lastly fiat as at 15, and within the projection 13 is pivoted the hasp 8 as in coilrloop or hasp bearing lug 16, the ends of the .hasp being hooked as at 17'.

Star ing with the position shown in Fig ure'3, wherein the hasp 8 has been. engaged with hook 7, the loop 12, carrying the cross bar of lever 9, is relaxed outwardly. Upon forcing the lever down, the lever loop or pivot 16 for the hasp swings downward about hook 7 as a center while the loop 12, carrying the cross bar of the lever, inwardly and upwardly,thereby forcing the lid tightly downon the box. After the hook 12 has passed outside of the plane of the hasp to the position shown in Figure 1, the fastener is locked and held so by the resiliency of wing 11, thus giving the effect of a toggle and holding the lower end 15 of the lever positively against plate 3.

This fastener will not accidentally come loose during shipment, even if not pinned or sealed, and yet can be easily and quickly opened by lifting the lever.

What I claim is:

1. A box fastener comprising a plate hav- J ing a resilient projecting end, a bent lever pivoted at the end thereof and having an intermediate inwardly extending coil loo within the bend on each side of the plate ent and a hasp carried by the loop and adapted i to be engaged with the box cover. 2. In a box fastener, the combination wit a supporting plate provided with an out- Wardly extending yieldable wing portion, of

a lever pivoted in said wing portion and out wardly spaced from said plate except at the lower end part of the lever, an inwardly projecting rigid bearing lug on said lever adjaoent its pivot, said bearing lug being located between the 'lever and plate, a hasp pivoted in said bearing lug and adapted to be engaged with the box cover, said hasp being adapted to be moved past said lever pivot, said lever at the bearing lug being spaced from the plate at leastas much as the yieldable wing portion, said plate being provided
